Ngaba i-tetrarahydrofuran imveliso eyingozi?

I-Tetrarahydrofuranyindawo yemichiza ngefomula yemolekyuli c4h8o. Lulwa lungenamibala, ulwelo olunokutsha olunevumba elimnandi. Le mveliso sisinyibilikisi esiqhelekileyo kwimizi-mveliso eyahlukeneyo, kubandakanya amayeza, iiplasitiki kunye nemveliso ye-polymer. Ngelixa ineengozi ezinokubakho, iyonke, i-tetrarahydrofura ayiyona imveliso eyingozi.

Umngcipheko omnye weI-Tetrarahydrofurankukuvutha kwayo. Ulwelo lune-flashpoint ye-S114 ° C kwaye inokuyifaka ngokulula ukuba iza kunxibelelana nespark, idangatye okanye ubushushu. Nangona kunjalo, lo mngcipheko unokulawulwa ngokulandela ukugcinwa okukhuselekileyo kunye neenkqubo zokuphatha. Ukunciphisa umngcipheko womlilo kunye nokuqhushumba, kubalulekile ukugcina imveliso ikude nemithombo yokusebenza kwaye isebenzise umoya ofanelekileyo.

Enye ingozi enokubakhoI-Tetrarahydrofurankukukwazi kwayo kubangela ukucaphuka kwesikhumba kunye nokutsha kwamakhamamikhali. Xa ulwelo luza kudibana ngqo nolusu, kunokubangela ukucaphuka, ukubomvu nokudumba. Lo mngcipheko unokuncitshiswa ngokunxiba izixhobo ezifanelekileyo kunye nezixhobo zokukhusela ngelixa uphatha imveliso. Iigloves, i-goggles, kunye nezambatho ezikhuselayo zinokuthintela ukubonakaliswa kwesikhumba.

I-TetrarahydrofuranIkwangulwelo oluguqukayo, oko kuthetha ukuba linokuvula ngokulula kwaye inike ingozi yokuphefumla. Ukuboniswa ixesha elide kubaphunga kunokukhokelela kwisikizi, iintloko, kunye neengxaki zokuphefumla. Nangona kunjalo, lo mngcipheko unokuthintelwa ngokusebenzisa imveliso kwindawo enomoya kwaye uphephe ukubonakaliswa ixesha elide.

Ngaphandle kwezi ntlungu zinokubakho, iTetrarahydrofura yimveliso eluncedo kakhulu. Iqhelekile isetyenziswa kumzi-mveliso wamachiza njengesolwvent yezithako ezisebenzayo. Kukwasisiselo esixabisekileyo kwimveliso yee-polymers kunye neplastiki, apho ivumela ukulawulwa ngokuchanekileyo kwiimeko zokulungisa kunye neempawu zokugqibela zemveliso.

Ngapha koko, le mveliso kulula ukuyiphatha kwaye inetyhefu esezantsi. Ibonisiwe ukuba inemigangatho ephantsi yetyhefu kwizifundo ezikwizilwanyana, iyenza ikhuseleke ukuze isetyenziswe kwiinkqubo zoMveliso. Le mveliso ikwanjalo ne-biodegrades, intsingiselo iqhekeza ngokwemvelo ibe yinto engenabungozi ngokuhamba kwexesha.

Ukuqukumbela, ngelixa kukho imingcipheko enxulumene nayoI-TetrarahydrofuranEzi ngcipheko zinokulawulwa ngokulandela inkqubo yokuphatha kunye nokugcina. Ukusetyenziswa kwayo ngokubanzi kumashishini ahlukeneyo kunye netyhefu ephantsi, uTetrarahydrofuran yimveliso ekhuselekileyo nexabisekileyo edlala indima ebalulekileyo kwiinkqubo zanamhlanje. Logama nje isetyenziswa ngokuchanekileyo, akukho sizathu sokuthatha imveliso eyingozi.
